Abstract
Embodiments of the present disclosure include a deployment system including an actuator. The deployment system also includes an actuator arm coupled to the actuator. The deployment system further includes a crank rotatably coupled at a pivot point. The deployment system also includes a first link arm coupled to the actuator arm at a first end and the crank at a second end. The deployment system includes a second link arm coupled to the crank at a first end and a deployment arm at a second end, the second link arm transmitting rotational movement of the crank to the deployment arm.
Claims17
A system for radially extending a deployment arm of a downhole tractor, the system comprising:
- an actuator that supplies a linear force along a tractor axis;
- an actuator arm coupled to the actuator at a first end and a first link arm at the second end, the actuator arm translating the linear force to the first link arm;
- a crank rotationally coupled to a housing of the downhole tractor, the crank being coupled to the first link arm;
- and
- a second link arm coupled to the crank at a first end and to the deployment arm at a second end, the second link arm translating rotational movement of the crank to the deployment arm to drive rotational movement of the deployment arm about a deployment axis.
A deployment system for a tractor, the deployment system comprising:
- an actuator, the actuator providing force in a linear direction substantially parallel to a tractor axis;
- an actuator arm coupled to the actuator;
- a crank rotatably coupled to at least a portion of the tractor at a pivot point;
- a first link arm coupled to the actuator arm at a first end and the crank at a second end, the coupling to the crank being proximate a top of the tractor and substantially aligned with the pivot point;
- and
- a second link arm coupled to the crank at a first end and a deployment arm at a second end, the second link arm transmitting rotational movement of the crank to the deployment arm.
